Eco-Celeb: Sharon Lawrence

When not playing professional adulteress Maisy Gibbons on Desperate Housewives, Sharon Lawrence has been busy sitting on the board of ECO and campaigning to protect coral reefs. As a certified diver, she's sorry to see reefs being mined so that coral can be ground into calcium supplement tablets. Some doctors agree with her that osteoporosis-preventing calcium can be obtained in healthier, dietary ways—healthier for the reef and for the human—since coral can contain traces of nasty elements like uranium. "I think the parallels between our health and reef health are obvious," she says. "Both are the foundations of entire ecosystems, one global and one individual. We have to protect both in order to ensure a healthy future." So eat broccoli instead of coral! ::USATODAY.com [by KK]
